HAND-STAMP.

Specification of Letters Patent No. 13,308, dated July 24, 1855.

To all whom it may concern:

Be it known that we, JOSEPH HARRIS, Jr., and ELBRIDGE HARRIS, of Boston, county of Suffolk, and St-ate of Massachusetts, have invented a new and useful Improvement in Hand-Stamp Printing-Presses; and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanyingA drawings and.

to the letters of reference marked thereon.

rlhe nature of our invention consists in a new mode of hand stamp printing.

To enable others skilled in the art to make and use our invention we will proceed to describe its construction and operation.

Figure l is a side elevation, Fig. 2 is a longitudinal section, Fig. 3 is a plan, Fig. 4 front View.

The letter A is a piston, which passes through cylinder B and has at its end a die, marked C. The arms D D of the cylinder extend to the sides of the frame E, and become a fulcrum, by turning on their journals and boxes marked F F. The box being stationary gives the whole when operated an oscillating motion for the purpose of inking the die, when passing over the ink roll G. The roll turns upon the journals and boxes H H, having a spring connected for the purpose of allowing the ink roll to have an adjusting motion.

The letters J J are adjusters, being attached to the arms or fulcrum D D, and are placed on both sides of the cylinder B and near the sides of the frame E, and are operated by the same motion with the die, and comes in contact with the ink roll boxes H H for the purpose of adjusting the roll to meet the die to be inked.

The let-ter K is a bed plate, upon which the article to be printed is placed before receivlng an impression.

The distance through which the cylinder B is allowed to oscillate is regulated by means of the checks L L and M M, which are attached to the frame E, the one above and the other below the journals F F, against which the adjusters J J come in Econtact at the limit of vibration.
